AEROPLANE.

To ZZ whom t may concern.' i s Be it known that I, GEORGE WELIKI, a citizen of Russia, residing at Hamilton, Ontario, Dominion of Canada, have invented certain new and useful Improvements in Aeroplanes, of which the following is a specication.

This invention relates to improvements in aerialconveyances, and particularly to apparatus of thisnature which will ascend and descend'in substantially vertical planes.

It is the object of the invention to provide an aeroplane of this character which is ofl an extremely simple construction and which is provided with a special steering and pro-v peller controlling means under the direct control of the operator, and which is capable of locomotion in horizontal, and also substantially vertical directions.

With these ends in view the invention consists in the novel construction and adaptation of devices, as will be hereinafter more fully described and claimed.

ln the accompanying drawings- Figure 1 shows an areoplane constructed according to the present invention in side Fig. 2 is a (top plan view 'of the same, partly in section on line 2 -2 of Fig. 1. The frame 10 of the aeroplane carries the wing l1 and cross-braces 11 and -12 and a flooring 13. To the bottom 14 is secured in a frame 15 the customary starting and landing Wheels 16, and to the ooring 13 a bracket 17 carrying the shaft 18 for the lifting propellers 19. "i

Upon the flooring 13 a seat 20 for the operator is arranged and infront of thesame the steering wheel and shaft 21 and 22 respectively 'for steering the aeroplane by' means of the tail 23 in the customary manner. Seat 20 and steering wheel and shaft 21 and 22 are located within a chassis 24, at

the forward wall of which the motor is arranged withn a casing'25 provided with an exhaust pipe 26. The shaft 27 of the motor extends from the front of the casing 25, and

its forward end is supported in a bearing 28 upon a post 29 on the flooring 13.` Intermediate its length the shaft 27 carries acoupling sleeve 30 slidablyarranged on said shaft whichin turn carrles a bevel gear 31 rotating therewith. To the sleeve 30 a 'rod 32 is plvotally connected as at 33,-., the free Specification of Letters Patent.

bevell gear 31 is in mesh with another bevel gear 37 on a vertical shaft 38 extending through the floorin 13 andcarrying below said flooring a bevel gear 39 in mesh with a similar bevel gear 40 on the shaft 18 of the lifting propellers 19.

The shaft 18 carries at its ends bevel gears 54 in mesh with bevel gears 55 on the shafts 53 of the propellers 19. Bearings 57 and 58 are provided for carrying shaft 18 under the flooring 13.

In front of the bevel gear 31 another sleeve 40 is slidably arranged upon shaft 27 .car-

rying a bevelY gear 41 rotating with said shaft. With lthis sleeve the rear end4 of a rod 42 is pivotally secured as at 43, the front end of which is pivotally secured near the handle 44 of a lever 45 in easy reach of the operator, which lever is also pivoted as at 46 on the ooring 13. y

A shaft 47 is arranged parallel to` shaft 27 above the same andis supported in a bearing 48 on post 29. The rearward end of shaft 47 extends beyond the bearing and carries a bevel gear 49 adapted 'to be engaged by bevel gear 41 upon suitable operation of the lever 45. The shaft 47 carries at its front end beyond the frame 10 a driving propeller 50. v

A gas bag 51 is provided underneath the wing 11 and is secured tothe frame by means of a hanger 52 secured on a hook 53. This gas bag is intended as a life-saving devicey for the operator in case of accident.

The device voperates as follows:

If the Operator desires to ascend. Vhe starts the motor and couples by means of the lever 34 Iand sleeve 30 the bevel gears 31 and 37 for the operation of the shaft for the lifting. propellers 19. When the plane has reached a certain level, he operatesk lever 45 to shift sleeve 40 and bring bevel gear 41 into mesh with bevel gear 49 for the rotation of shaft 47 of the driving ipropeller 50, and at the same time Operates bevel gears 31 and 37. The steering is effected by the Operation of the tail piece 23 by means of the steering wheel 21 and coper-` ating parts.

ters Patent of the United States is 1. In a motor operated aeroplane of the character described, including a shaft forthe motor, and lifting and driving propellers With their shafts, bevel gears on said shafts, and means for shifting the bevel gears on the motor shaft into and out of engagement with the bevel gears on the shafts for the lifting and driving propellers respectively, substantially as described. v

2. In a motor operated aeroplane of the character described, including a Vshaft for 15 the motor andglifting and driving propellers with their shafts, bevel gears von said engagement with \th'e bevel gears on the shafts for the lifting and drivingpropellers,

lsaid means comprising coupling sleeves'slidably arranged on the motor shaft, horizontal rods pivotally secured Withy one of their ends to said sleeves respectively, and hand levers near the operators seat pivotally connected to the opposite endsl of said horizontal rods substantially as described and for the purpose set forth.

In testimony vvhereof I have axed my signature.
